image_2024-02-04_020354202.pngHi there everyone, I was just wondering what the purpose of the 4 wires were in the RPi 5 active cooler unit. I thought there would be 2 but the 4 confuse me. Is it for a temp sensor? But RPi 5 has built in temp sensors. I have no idea why there are 4 wires. How would I go about viewing those in C code as well if anyone knows?
Ground, Power, PWM control to cooler, Tachometer output from cooler.

The same 4 connections are used by the fan in the Raspberry Pi Cooling Case -
